Scammed?! ,

Seems to be working great

I don’t have perfect pitch, so this is a matter of trust. But the app is incredibly easy to use when tuning my harpsichord. I feel like a bit of a cheat for not relying on my ears. But, it makes me more confident that others will enjoy listening when I play.

Developer Response ,

You are absolutely right not to trust the app! It is much easier to simulate a stable result than to analyze the many frequencies and determine the correct result. That's why I always recommend to test a tuner with some test tones before using it. This way you know that you can trust the tuner.
Thanks for the rating!
